WOW sure did not see this one coming. Price is reasonable and it looks like it has some nice features. I doubt it will take the place of my beloved FLM tranny case on my Rusty but I would definitely consider it for some future build on a Traxxas 2wd vehicle.

It looks to me like you would be able to use some anti squat shims on the tranny case as well, that is a very good thing IMO, maybe more so for the Rusty and Stampede than the Slash because they are more wheelie prone.

If I had to be picky, toe blocks need to be sold separately, and offer 4* toe blocks also. It looks like you need the RPM rear bumper mount, their wording is unclear to me anyways. Just thought I would mention that for those thinking of making a purchase.

I'll never say anything bad about rpm,the products rock.
But fast lane machine trans and sealed diff,sounds and looks wicked,Need deeper pockets,but from what Ive heard from owners,which are few,probable due to the price? Say there the best! looks an performance.
And of course durability,does it get any better?

Iv been drooling over the FLM trans case since its release and then they added the sealed diff, ughhh, somebody please stop me. I have been spending most of my RC budget on my 4x4 this past year, but I have since finished that project. So, you know where my budgets is going, my 2x4 needs a little lovin.

The part ships in Jan 2013 - the 7th I believe it says at the bottom of the page - they better make a lot of them there's going to be real demand for them I think. Oh yes and if my memory serves me right the toe blocks are sold seperately. I expect to see someone do aluminium versions of the blocks as well.

And I'll put money of a front block of some description from them soon.

Finally! Somebody put some thought into a transmission for Traxxas vehicles. Sure the FLM is an awesome trans, but it's very expensive compared to the RPM and, realistically, the motor mount plate is the only thing that really needs to be aluminum. A full aluminum housing is cool for most people, but overkill for myself. The replaceable arm mounts are another awesome detail. A simple solution for rear toe on the Rustler and Stampede, but also a variety of toe options for the Slash.

IMO, this is the best aftermarket product I've seen in a very long time for Traxxas Rustler platforms. I've been wanting to build an LCG Slash, but couldn't find a trans that suited my needs. The Proline was the closest thing I found, but was a miserable failure. With this RPM trans you can use all the aftermarket slipper conversions (especially the AE/STRC), a variety of different internal gear options (versus the PL which had to use their diff), adjustable rear toe, and also have the motor stay where you put it and run cooler with the aluminum plate. Big score for RPM!!!!!!

Just a thought here, but if the arm mounts are anything like the original Traxxas Magnum trans, you will have a wide range of toe settings. With the older Traxxas trans you could swap the -1 mounts to the opposite side, giving 1 degree of positive to, which would bring the total to 2 degrees instead of three. So, the possible settings were 0, -2, -3, -4. More fine tuning could also be made with different rear carriers. I'm starting to get very excited about this.

EDIT: Oh well, looks like for now there's only 0 and 3 degree mount. That will limit the options, but hopefully RPM will take the hint and make some other arm mounts so we can fine tune the rear toe settings.

Harry said it all. What a wonderful hop up. Thank you rpm. Funny that you can now get the trans (that actually works lol)that proline should have built for about 70$ total including gears and bearings and an associated slipper setup... Msrp is 30$ Is that $20 from the discounters?

Don't tell RPM, but I would pay even more just so I don't have to deal with all the other failed attempts out there.

Hopefully somebody has a definitive answer for this. I'm guessing it's yes, but would like to know for sure. Will the FLM sealed diff work in the standard Traxxas trans? If so, that's gonna be my new Slash setup. RPM trans, FLM diff, and TRX steel idler along with the STRC top shaft/AE slipper. Perfect setup IMO.

My only concern with the RPM would be if there's too much flex in the housings. RPM is known for their flexible suspension parts. Hopefully the trans cases will be beefy enough that it won't be an issue. Plus, having the arm mounts separate from the trans cases should reduce a ton of stress on the trans cases.

In the pede forum, a post brought up a concern. Only one screw holding the susp mounts to the trans? I think one will do fine. Just wondering your thoughts...

I just noticed what you're talking about. Why do the mounts even bolt to the trans at all? They have the two 4mm screws that attach them to the chassis, so I don't see any need for them to attach to the trans at all. My first thought when I looked at the pics was to cut the tab off the trans altogether. If you did, you would also gain full range of squat angle adjustment.

Here's a pic of the original Traxxas Magnum trans. The mounts attach to the chassis only. They're completely independent of the trans. I guess maybe the reason for the setup on the RPM trans is to add a little more rigidity to the arm mounts?

Yes. The FLM diff will work in a stock case.
This RPM case looks good and well thought out. I currently use the FLM case and love it. It has detachable arm mounts which is one of the reasons I like it.

well after skimming through the 30 posts on this, I didnt see any input about the material used. SOOOO.....

.....in my experience with RPM products, the material is softer than stock. As you can see, the screws go into the case and not through and into the metal plate as Traxxas use to do. I think this my be an issue and something that may need to be rectified.

According to the Jang, RPM used a stiffer material for the case. BITD, RPM made cases for the AE Stealth transmission, which were very good, as well as complete chassis for AE. Although they have been focusing on the bash market for the past decade or so, they do know how to make stiff, race-type stuff, and have done well in that market in the past. I assume that the lifetime guarantee would get more of a workout if the arms and bumpers were made of the stiffer material, although I would buy them if they were. As it stands, RPM suspension parts are a durability modification that does nothing for performance, and, in some instances, actually hurts performance.
My cases have not arrived yet, but I expect them to be of the same high quality that all of the other RPM parts are.

In the first pic you can see that the screws go through the metal plate, then into the case.

The second pic shows the top plate screw is able to go all the way through, only needing a washer and nut, and a longer screw. As for the lower plate screw I see an opening showing that with a longer screw, you can add a washer and nut. If I misunderstood the wording in your post, my apologies, only wanted to clarify,. if needed I see a way to solve your concerns. As we all know that with self tapping screws, you only get one chance when first assembling then.

Wish mine was here. I'm going to cut the top out of the "motor pocket" for fan clearance. I skipped the PL trans, even though I was very excited about it, due to all of the durability problems, so this one better be as good as it looks!
